6 Claims- (Cl. 189-76) This invention relates to improvements in channelstructures and more particularly to metallic channel structures forengaging around edge margins of sheet elements which may be panes ofglass, or sheets and panels of other materials, which are to be mountedwithin a metallic frame for protectively supporting the sheet element asa window or panel in a building or for serving in the nature of ashipping crate, or the like, to protectively enclose the edge margins ofone or more glass panes, panels, or the like. The invention provides animproved channel structure, for the mentioned general purposes, whereinchannels of metal and of resilient cushioning material are combined andutilized in a novel manner to attain novel results and effects.

The invention is herein illustrated and described as it may be embodiedin a window frame which may be of the jalousie orany other type, but itshould be understood that the disclosed channel structure is not limitedin utility to window frames but may be employed wherever it becomesnecessary or desirable to protectively enclose edge margins of sheetelements as a permanent frame for single sheet elements of glass, or thelike, or as a permanent or temporary protective frame for edge marginsof a single sheet element, such as a structural panel, for example, or aplurality of such panels, grouped together for shipment.

The present invention contemplates a novel channel structure fabricatedfrom elongated framing stock of simple construction, lengths of whichmay be cut whenever desired into suitable sections that need only bejoined at their ends to provide without more a weather-proof andnon-rattling support or protector for a glass pane, a panel, or aplurality of the panes or panels grouped together, as for shipment.

An object of the present invention is to provide framing stock of theforegoing type comprising telescoped channels, the outer one beingcomposed of a relatively stifi resilient material such as sheet metal,and an inner one being composed of a relatively soft compliant materialsuch as rubber, the channels being permanently connected by beads in theextremities of the legs of the outer channel which tightly pinch theextremities of the legs of the inner channel.

Another object of the present invention is to provide a channelstructure comprising sections of framing stock of the foregoing typewhich are connected at their ends by specially designed angle bars, thearms of which extend between bight portions of two telescoped channels.

Other objects of the invention will in part be obvious and will in partappear hereinafter.

The invention accordingly comprises the product posessing theproperties, features and relation of components which are exemplified inthe following detailed disclosure,

and the scope of the application of which will be indicated in theappended claims.

For a fuller understanding of the nature and objects of the invention,reference should be had to the following United States Patent PatentedOct. 15, 1957 detailed description taken in connection with theaccompanying drawing wherein:

Fig. 1 is a front elevation of a window embodying the present invention;

Fig. 2 is a perspective view of a fragment of the window of Fig. 1 withportion broken away, and with parts in section, the section being takenalong the line 22 of Fig. l;

Fig.3 is a perspective view of one of the corner components of thewindow of Fig. 1; and

Fig. 4 is a side elevation of a modified wrap-form of framing channel.

Fig. 1 illustrates a jalousie window 10 removably secured within asuitable frame 11 by a series of pivotable fasteners 12. Window 10includes a glass pane 13 and four framing sections 14 secured at theirmitered ends by four corner brackets 15.

Sections 14 are shown in detail in Fig. 2 as comprising an inner channel16, a medial channel 17 and an outer channel 18. Inner channel 16,preferably, is composed of a relatively soft compliant material, forexample, a rubberlike material such as natural rubber or neoprene, asynthetic plastic material such as polyethylene or nylon or a fibrousmaterial such as felt or asbestos. Inner channel16, which is designed tosnugly engage the edges of pane 13, serves as a weather-proofing andshock absorbing seal or cushion. Medial channel 17 and outer channel 18preferably are rolled into shape from suitable sheet metal blanks.Medial channel 17 is coextensive with inner-channel 16 so that its armshave the leverage and its bight portion'the proximity to tightly gripand effective ly support the edges of pane 13 with the inner cushioningand sealing channel 16 intervening between them. The

legs of outer channel 18 are longer than the legs of medial and innerchannels 17 and'16 so that the bight portion 20 of the outer channel isspaced from bight portions 21 and 22 of the the medial and innerchannels. Bight portion 20 is provided with a reentrant step having ahorizontal portion 23 and a vertical portion 24, as viewed in Fig. 2.Vertical portion 24 preferably is provided with a strip 25 of softcompliant material which may be cork or any of the materials describedabove in connection with inner channel 16. Strip 25 serves as aweather-proofing and shock absorbing seal between sash 10 and frame 11.

Channels 16, 17- and 18 are permanently connected to each other withoutadditional discrete components as follows. The extremities of the legsof channels 17 and 18 are reversely bent to provide beads 26, 26 and 27,27. Associated beads 26 and 27 are shaped together to permanentlyinterlock the outer two channels and at the same time to firmly pinchthe extremities of the legs of inner channel 16. The beads additionalyserve as guides tospread the legs of the composite channel when theedgeof: a glass pane is introduced.

The ends of sections 14 are connected by angle brackets 15 that havebeen stamped, cast or otherwise formed into the shape shown in Fig. 3.Each bracket 15 has two coplanar arms 30 and 31 which are provided,along their inner edges, with ridges 32 and 33 lying in planesperpendicular to the common plane of the arms. As will be seen in Fig.2, the thickness of arms 30 and 31 is substantially the same as thedistance between vertical portion 24 and the adjacent parallel portionof the longer leg of outer channel 18. Furthermore, ridges 32 and 33 arespaced from the outer edges of the arms by distances which permit ridge32 to immediately underlie horizontal portion 23 of one framing section14, and ridge 23 to immediately underlie horizontal portion 23 of anadjacent framing section 14, when the outer edges of the arms underliethe outermost portions of bights 20, 20 of the two sections. The armsand ridges of brackets 15 may be welded or otherwise secured to thereentrant step portions sections which when joined by brackets of theabove description provide a weather-proof and non-rattling sash for aglass pane of any chosen size. However,' the cut sections may be joinedtogether by any suitable means,

and may be produced in sizes suitable for engaging over edge margins ofvarious sheet elements for any of a variety of purposes, such as forprotecting the edges of panels and the like during handling andshipping.

In the interests of economy, it sometimes may be desirable to producethe framing sections in continuous strip form with cut-out notchessuitably spaced apart so that the strip may be Wrapped around theedgesof a pane or panel, or a plurality of grouped together panes or panels,and extend continuously around all four sides thereof. Fig. 4 shows sucha continuous strip 14 which has been notched at predetermined spacedlocations 34 where corner bends are to occur, with complementary endportions adapted to be brought together and secured at one corner of theframe. The 90 angular'notches may be cut in the channels prior to theirbeing assembledor after assembly. Corner brackets 15, or the like, ateach of three of the corners may be loosely inserted at the time ofbending the frame. Each of these brackets will be retained as a cornerreinforcement by the right-angularly related sides of the frameextending from that corner. The bracket 15 at the fourth corner, Wherethe mitre joint is to be effected, may have the opposite end portionswelded or otherwise rigidly secured to it for strengthening the mitrejoint. Obviously, all of the corner brackets may be welded or otherwisesecured to the outer channels if this is considered desirable forstrength at the corners.

Since certain changes may be made in the above product without departingfrom the scope of the invention herein involved it is intended that allmatter contained in the above description and shown in the accompanyingdrawing, shall be interpreted in an illustrative and not in a limitingsense. 1
